Abstract
In this paper, the photocatalytic decomposition of composite catalysts for hydrogen production was investigated from two aspects of the preparation of the catalyst and the photocatalytic reaction system. The catalyst preparation conditions which affect the photocatalytic hydrogen production activity was considered, which include the doping amount of SiO2, effect of perovskite complex, catalyst preparation temperature and preparation time. In the photocatalytic reaction system on the hydrogen production activity, the effects of catalyst dosage and sacrificial agent concentration on the hydrogen production rate were investigated, respectively. The methods and materials provided herein can utilize high-temperature heat generated by solar focusing as a source of energy and H2O as a starting material, which can stably and rapidly produce H2 at a lower reduction temperature compared to the reported results.
